Zimbabwe’s mining companies should invest heavily in new technology if their revenue are to increase, said Deloitte and Touche chief executive Tawanda Gumbo.

Gumbo, speaking at the 73rd Chamber of Mines AGM late last week, said some mining companies' production levels and earnings could grow if they invested in technology in all their operations.

"The cost of doing business could be reduced if the mining companies invested in new technology as solutions and applications reduce workload while increasing production in most cases," Gumbo said.

"We need new technology. Technological development increases mining operations and efficiency. This has been proven globally and the same can happen in Zimbabwe," he said.

Zimbabwe’s mine revenues in the first quarter rose 10,4% to $454 million on the back of higher production numbers. The gold sector was the star performer, contributing $187,9 million, followed by platinum ($121 million), palladium and high carbon ferrochrome.
